Fiber Driver Modules
The Fiber
Driver Modular CWDM system offers two types of data channel cards: the
Multi-Rate Transponder and the SFP (or GBIC) to SFP (or GBIC) Media Module.
Configured with CWDM-specific SFP (Small Form Factor Pluggable) optical
transceivers, and connected externally to the Mux/Demux via optical jumper
cables, the channel cards generate and maintain the active data connections.
Deployed along a WDM trunk at customer service points using MRV
Communications' passive OADM technology, the Multi-Rate Transponder and
SFP-to-SFP Media Module can also be used to create a sophisticated Add/Drop
topology.
The Multi-Rate Transponder performs full clock and data
recovery (3R) per channel at any user selected data rate from 65 Mbps to 2.7
Gbps (65 MHz to 2.7 GHz). By comparison, the SFP-to-SFP Media Module is data
rate transparent and works automatically with any data rate from 100 Mbps to 2.7
Gbps (100 MHz to 2.4 GHz) while performing 2R functions.
Built into
every CWDM Modular system is extensive In-Band and Out-of-Band management
capabilities, including full support of SFP digital diagnostics as per SFF-8472.
Management provides real-time access to information such as transceiver type
(protocol, range, vendor, etc.), operating temperature, TX/RX optical power,
power supply status, and transceiver supply voltage. Management also provides a
means for generating management alerts and warnings when system parameters fall
outside of their normal operating range.
